The VST KiDS survey will allow astronomers to make precise measurements of dark matter, the structure of galaxy halos, and the evolution of galaxies and clusters. The first KiDS results show how the characteristics of the observed galaxies are determined by the invisible vast clumps of dark matter surrounding them.http://phys.org/news/2015-07-huge-survey-dark.html

These nuclei are located at the boundary of the known nuclear chart, and despite their short lifetimes—measured in milliseconds—these nuclei imprint their properties on the chemical composition of the universe. This research, published in Physical Review Letters, is a major step forward toward providing an experimental ground for models of the mysterious astrophysical "r-process" which is believed to be responsible for the creation of many of the elements in the universe heavier than iron.http://phys.org/news/2015-05-precise-half-lives-previously-unmeasured-nuclei.html

General Physics Wed, 22 Apr 2015 04:00:01 EDTnews348855267Why do measurements of the gravitational constant vary so much?(Phys.org)—Newton's gravitational constant, G, has been measured about a dozen times over the last 40 years, but the results have varied by much more than would be expected due to random and systematic errors. Now scientists have found that the measured G values oscillate over time like a sine wave with a period of 5.9 years. It's not G itself that is varying by this much, they propose, but more likely something else is affecting the measurements.http://phys.org/news/2015-04-gravitational-constant-vary.html

A thick layer of dust covers the glaciers, so they appear as surface of the ground, but radar measurements show that underneath the dust there are glaciers composed of frozen water. New studies have now calculated the size of the glaciers and thus the amount of water in the glaciers. It is the equivalent of all of Mars being covered by more than one meter of ice. The results are published in the scientific journal, Geophysical Research Letters.http://phys.org/news/2015-04-mars-belts-glaciers-frozen.html
